1) In recent years many states have passed mandatory seat belt laws. The total number N of states that had a seat belt law in effect : years after 1984 is given by the graph below. Express the number of states with seat belt laws in effect in 1987 using function notation. Then use the graph to estimate its value. Make sure to include appropriate units. Pyeare b) In what year were there seat belt laws in effect in 40 states? When was the graph concave up? Explain how the number of states with seat belt laws was changing during this period (i.e. increase, decrease at what kind of rate). sasN

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
